For former West Coast Eagle Brent Staker, the more things change with his "ruthless" move to Brisbane, the more they stay the same.

Staker, set to make his Lions debut against his old AFL club on Saturday night, feels he hasn't moved house let alone shifted from one side of the country to the other.

The 25-year-old is sharing digs with Troy Selwood, the identical twin of his long-time Perth housemate Adam Selwood.

Not only do the brothers look the same but they sound the same and act the same.

"It's different city, different house, same bloke," Staker said on Wednesday.

"They're very similar characters. They have the same sense of humour, the same laugh.

"You get out of bed in the morning and you don't miss a beat, you feel like you're back in Perth."

While Troy will miss the round one clash at the Gabba following an injury-affected pre-season, Adam will be a significant member of the improving Eagles midfield.

"It's funny in the end that Stakes ended up going to Brisbane," Adam said.

"It's a bit strange how he moved from one Selwood to the other - I don't think any girls have done that."

With Selwood well versed in opposing close mates - playing against Troy at Brisbane and younger brother Joel at Geelong - he felt he held the personal advantage.

"It's good coming up against good friends and I've had it a bit coming up against my brothers," he said.

"So it might feel a bit more weird for him."

One of six seasoned Lions recruits, Staker has quickly settled in at the Lions since moving in October and will play as a third tall beside Jonathan Brown and Brendan Fevola.

The 196cm-tall utility, who was restricted to just six senior games in 2009 due to hand injuries, admitted it was a tough call for him to leave the Eagles but asked for a trade a year before his contract expired to shore up his future.

"I had to make a ruthless decision and that's what I made," he said.

Lions coach Michael Voss hasn't asked for much insight into West Coast from Staker but the new recruit was happy to voice his opinion with the Eagles' defensive match-ups.

According to Staker, Darren Glass will take Fevola, Eric Mackenzie will be on Brown and either Matt Spangher or Brett Jones will line up on himself.

But he warned rivals will struggle to contain "twin towers" Brown and Fevola all season due to their flexibility in the forward 50.

"I think that's the exciting part of it, it's not predictable," he said.

"It's going to be a headache for many teams, because one week they will do this but the next week they will do two different things.

"Every game will change, every minute."
